Introducing technologies such as the Mewis duct indicate significant strides in optimising propulsion systems for greater energy efficiency.

Several shipping companies like Cosco Casablanca are currently making significant investments within the development of new fleets that run using liquified natural gas (LNG), which will be the most advanced level and fuel-efficient solution available. These ships have slow-speed tri-fuel engines that run on compressed boil-off gasoline through the cargo tanks as fuel. During transportation, the LNG changes its state to fuel due to slight heat increases, which in turn causes boil-off that occurs. To help make these ships a lot more environmentally friendly, they have been equipped with an higher level exhaust recirculation system that significantly reduces nitrogen oxide emissions. Also, the vessels are equipped with a gasoline combustion system that lowers the potentiality of releasing methane into the atmosphere.

A significant task these days for the global shipping industry is to reduce its environmental footprint, an attempt that will require a multipronged approach. But this might be no effortless task. Based on specialists, marine engines are complicated to change, and even if engineers can modify them in a manner that could make them produce less CO2, modifying shipping fleets would be quite expensive. Hence, progress is slow in this domain. However, a range shipping companies like DP World Russia, are making impressive changes and striving to find solutions that reduce carbon dioxide emissions. And they are gradually putting those changes to work on their fleets of ships. They are increasingly meeting the benchmark requirements of the energy efficiency design index. Indeed, businesses like Morocco Maersk are creating effectiveness in the commercial delivery sector. A fantastic case of technical progress is visible within the improvement of the Mewis duct. This is a cylindrical channel that has integrated fins, which is located in the front of the propeller. As the a ship moves through water, it creates a wake current that may be turbulent and result in energy wastage. However, the Mewis duct directs this wake current towards the propeller and streamlines the water movement. Additionally, the fins within the duct twist the current before it reaches the propeller blades, that leads to increased energy efficiency of the propulsion system.

Some shipping companies are using self polishing coatings in the hulls of the ships. This, according to maritime experts, helps in avoiding marine organisms from clinging on the hull where they result in a significant drag. So when vessels have the ability to eliminate this drag by using the this layer, they could also make their vessels more effective. There are many efforts to enhance a ship's effectiveness, including complex engineering answers to simple things such as changing bulbs. For instance, vessels can conserve energy and start to become more environmentally friendly by changing conventional incandescent light bulbs with Light-emitting Diode lights, which consume less electricity and endure for decades.
